Persistent Store Coordinator
The persistent store coordinator (NSPersistentStoreCoordinator) is the intermediary between the actual files that object data is stored in and the object model that the app interacts with. An app typically does not interact with a persistent store coordinator beyond just instantiating it when setting up the Core Data environment. The persistent store coordinator can manage communication with more than one persistent store so that the details of how the data are stored is hidden. After the persistent store coordinator is set up, a persistent store needs to be added to it to be able to access data.
